A measure of reflected acoustic energy as a function of immitance, as in middle ear impedance.

reflectance

(rē-flek′tăns)
The fraction of total light reflected after it hits a surface, and the angle at which it is reflected. It is the inverse of absorbance.

diffuse reflectance

The reflectance of light from a rough or nonpolished surface in which the radiant energy tends to scatter. The angle of reflectance does not equal the angle of incidence.

spectral reflectance

The reflectance of light from a polished surface in which the angle of reflectance equals the angle of incidence.

reflectance 

A measure of reflection equal to the ratio of reflected luminous flux Ε′ to the incident luminous flux Ε, i.e. ρ = Ε′/Ε. Syn. reflection factor. See Fresnel's formula.
